This revision increases the eMMC from 2GB to 4GB. We are making this change for several reasons:

1) Complaints from the community about lack of space left in the eMMC.2) For those worried about their eMMC wearing out, the added space will help in the area of moving the data around to prevent wear out. Assuming of course you don't try and use it all.3) Concerns over the long-term availability of the 2GB device. 4GB is currently the low end of the offering. This also gives us two sources.
